* windres.c (long_options): Add --use-temp-file and
|
||||
--no-use-temp-file options.
|
||||
(usage): Document.
|
||||
(main): Handle.
|
||||
|
||||
* windres.h: Update read_rc_file prototype.
|
||||
|
||||
* resrc.c (cpp_temp_file): New static variable.
|
||||
(istream_type): New static variable.
|
||||
(close_pipe): Delete function.
|
||||
(run_cmd): New static function.
|
||||
(open_input_stream): New static function.
|
||||
(close_input_stream): New static function.
|
||||
(look_for_default): Handle DOS directory separator. Use
|
||||
open_input_stream instead of popen.
|
||||
(read_rc_file): Likewise.
|
||||
|
||||
* binutils.texi: Document --use-temp-file, --no-use-temp-file
|
||||
options.

@item --use-temp-file
|
||||
Use a temporary file to instead of using popen to read the output of
|
||||
the preprocessor. Use this option if the popen implementation is buggy
|
||||
on the host (eg., certain non-English language versions of Windows 95 and
|
||||
Windows 98 are known to have buggy popen where the output will instead
|
||||
go the console).
|
||||
|
||||
@item --no-use-temp-file
|
||||
Use popen, not a temporary file, to read the output of the preprocessor.
|
||||
This is the default behaviour.

@item --help
